CVE-2017-5488

Multiple cross-site scripting (XSS) vulnerabilities in wp-admin/update-core.php in WordPress before 4.7.1 allow remote attackers to inject arbitrary web script or HTML via the name or version header of a plugin.

CVE-2017-5489

Cross-site request forgery (CSRF) vulnerability in WordPress before 4.7.1 allows remote attackers to hijack the authentication of unspecified victims via vectors involving a Flash file upload.

CVE-2017-5490

Cross-site scripting (XSS) vulnerability in the theme-name fallback functionality in wp-includes/class-wp-theme.php in WordPress before 4.7.1 allows remote attackers to inject arbitrary web script or HTML via a crafted directory name of a theme, related to wp-admin/includes/class-theme-installer-skin.php.

CVE-2017-5491

wp-mail.php in WordPress before 4.7.1 might allow remote attackers to bypass intended posting restrictions via a spoofed mail server with the mail.example.com name.

CVE-2017-5492

Cross-site request forgery (CSRF) vulnerability in the widget-editing accessibility-mode feature in WordPress before 4.7.1 allows remote attackers to hijack the authentication of unspecified victims for requests that perform a widgets-access action, related to wp-admin/includes/class-wp-screen.php and wp-admin/widgets.php.

CVE-2017-5493

wp-includes/ms-functions.php in the Multisite WordPress API in WordPress before 4.7.1 does not properly choose random numbers for keys, which makes it easier for remote attackers to bypass intended access restrictions via a crafted site signup or user signup.

CVE-2017-5610

wp-admin/includes/class-wp-press-this.php in Press This in WordPress before 4.7.2 does not properly restrict visibility of a taxonomy-assignment user interface, which allows remote attackers to bypass intended access restrictions by reading terms.

CVE-2017-5611

SQL injection vulnerability in wp-includes/class-wp-query.php in WP_Query in WordPress before 4.7.2 allows remote attackers to execute arbitrary SQL commands by leveraging the presence of an affected plugin or theme that mishandles a crafted post type name.

CVE-2017-5612

Cross-site scripting (XSS) vulnerability in wp-admin/includes/class-wp-posts-list-table.php in the posts list table in WordPress before 4.7.2 allows remote attackers to inject arbitrary web script or HTML via a crafted excerpt.

For Debian 7 'Wheezy', these problems have been fixed in version 3.6.1+dfsg-1~deb7u13.

We recommend that you upgrade your wordpress packages.
